The Strimko Object 


The object of the puzzle is to fully fill in the given grid with
missing numbers observing three simple rules. You have numbers 1
through 3 for a 3 x 3 grid; 1 through 4 for a 4 x 4 grid; 1 through 5
for a 5 x 5 grid; 1 through 6 for a 6 x 6 grid; 1 through 7 for a 7 x
7 grid; and so on. 





Three Simple Rules 





Rule #1 
Each row must contain
different numbers. 





Rule #2 
Each column must
contain different numbers. 





Rule #3 
Each stream must
contain different numbers. 










Strimko Example 





Start 
Let’s solve the easiest
3 x 3 Strimko logic puzzle stepbystep. 



Step #1 
In the second row only
one number is missing. Thus we can put in the grid our
first number, 3. 



Step #2 
In the diagonal stream
we can put in its top right cell only 1, and in its
bottom left cell only 2. One stream is fully filled
now. 









Step #3 
Now we can put two
missing 3’s; they must go in the middle cells of the
two opposite cornerlike streams. 




Step #4 
Finally, we have to
complete both cornerlike streams putting 2 in the top
vacant cell, and 1 in the bottom one. 




Finish 
Congratulations!
You have solved your first Strimko logic puzzle.
